Wondering if my chickens have sour crop?

[feliccp_]

I caught two of my hens have a white mucus exit their mouths today, it was cloudy and it seemed to just fall out, they didnt cough it up or anything. i researched and i read it could be sour crop? ive noticed recently one has had some ruffled feathers, and the two that threw up have had bad diarrhea. i live in texas so i thought it was the heat, but i checked her crop and it felt very full and squishy, like i could feel all the seeds inside or something. i checked the other girls crop and it wasnt AS bad but still pretty squishy. i read to quarantine them, and have them fast for 24 hours, and give them apple cider vinegar or epson salt. is it sour crop or could it be something else?

What time did you check the crops? Crops are usually empty and flat in early morning. They fill up as the day goes on while eating and drinking. Is there a bad or sour odor from the beak? Check them early in the morning to see if they have emptied. Here is a good article about crop treatments:
